A solid paper on automatisms and geometry. The lost points mostly come from conclusions left unwritten: the calculations are right, but the property used is not named.

Part B · Reasoning

Exercise 2

3 / 4 pts5 min

A triangle $A B C$ has $A B = 7.5$ cm, $A C = 4.5$ cm and $B C = 6$ cm. Is triangle $A B C$ right-angled? Justify.

AB2=7.52=56.25AC2+BC2=20.25+36=56.25so the triangle is right-angled

Feedback

The calculations are right and the equality $A B^{2} = A C^{2} + B C^{2}$ is correctly checked. The expected conclusion is missing: name the converse of Pythagoras’ theorem and state that the right angle is at $C$ , the vertex opposite the longest side.

Solution

Square of the longest side1 pt
$A B^{2} = {7.5}^{2} = 56.25$ .
Sum of the squares of the two other sides1 pt
$A C^{2} + B C^{2} = {4.5}^{2} + 6^{2} = 20.25 + 36 = 56.25$ .
Equality observed1 pt
We have $A B^{2} = A C^{2} + B C^{2}$ .
Written conclusion1 pt
By the converse of Pythagoras’ theorem, triangle $A B C$ is right-angled at $C$ .

Reproduction of a corrected Brevet practice paper in Coach: the mark out of the total, the overall feedback, then one question with its feedback, its solution and the marking scheme (sample content).

Two ways to sit a paper.

Simulation mode
Like the day of the exam: timed, full screen, no help. The paper is handed in automatically when time runs out.
Assisted mode
No timer. The AI tutor is beside you to help you understand a question, designed not to give you the answer: the worked answer is not passed to it.

How Coach works

Where these papers come from.

AI-generated, in the exam format
The papers are generated by AI and serve as practice material. Brevet: an “automatismes” section and a reasoning section, with Scratch programs when the exam includes them. Bac: two days, maths speciality, with and without a calculator, with Python.
The official past papers remain the reference
Past sessions’ papers and the exam’s rules are to be checked every year on Eduscol. Coach’s papers are practice papers, not official ones.
Within the curriculum
The papers follow the year’s curriculum. If a question looks wrong to you, tell us through the contact form: we check and we reply.
